Researchers now confirm that genome duplication drives evolution of species

Many wild and cultivated plants arise through the combination of two different species. The genome of these so-called polyploid species often consists of a quadruple set of chromosomes - a double set for each parental species - and thus has about twice as many genes as the original species.

Researchers find molecule that halts, reverts neurodegeneration caused by Parkinson's disease

The small SynuClean-D molecule interrupts the formation of the alpha-synuclein amyloid fibers responsible for the onset of Parkinson's disease, and reverts the neurodegeneration caused by the disease.

Environmentally-induced gene activity influences IQ test performance

Is there a link between differences in IQ test performance and the activity of certain genes? Researchers from Charité - Universitätsmedizin Berlin have shown that modifications in the structure of a specific gene have a negative impact on individual test performance.

Genomic ‘islands’ evolved from viruses can be converted into ‘anti-bacterial drones’

Genomic "islands" that evolved from viruses can be converted into "drones" that disable Staphylococcus aureus, bacteria that are often resistant to antibiotics and pose a threat to safe hospital care, a new study finds.

Study sheds light on how brain protein may be involved neurodevelopmental disorders

A study by researchers at Rockefeller University has shown that defects in a brain protein may underlie a number of neurodevelopmental disorders.

New test speeds up diagnosis of multi-resistant pathogens

Researchers at the University of Cologne and the German Center for Infection Research have made an important step towards speeding up the diagnosis of multi-resistant pathogens.

Environmental biologist explores how songbirds stay slim despite overeating

Noticing that songbirds, such as finches, never seem to get fat despite overeating at bird feeders, London environmental biologist Lewis Halsey wondered whether the amount of energy birds put into singing, fidgeting, or exercising could be adjusted in ways that regulate weight.

New research provides insight into the way human brain connects episodic memories to solve problems

Humans have the ability to creatively combine their memories to solve problems and draw new insights, a process that depends on memories for specific events known as episodic memory.

Scientists discover and characterize human skeletal stem cells

Human skeletal stem cells that become bone, cartilage, or stroma cells have been isolated from fetal and adult bones. This is the first time that skeletal stem cells, which had been observed in rodent models, have been identified in humans.

Six-year study of Hadza people reveals new insight into human cooperation

In the modern world, people cooperate with other people including strangers all the time. We give blood, tip providers of various services, and donate to charity despite the fact that there is seemingly nothing in it for us.

Ecstasy drug makes octopuses more social

When people take MDMA, the drug popularly known as ecstasy, a rush of serotonin, dopamine, and oxytocin produces feelings of emotional closeness and euphoria, making people more interested than they would normally be in connecting and sharing with other people.

Researchers propose mechanism by which ASTN2 protein defects lead to brain disorders

In the brain, as in business, connections are everything. To maintain cellular associates, the outer surface of a neuron, its membrane, must express particular proteins--proverbial hands that reach out and greet nearby cells. And, like a creepily long handshake, surface molecules can overstay their welcome: A protein that lingers too long on the membrane may compromise the connections, or synapses, between cells.

Overlooked immune cells could play a key role in cancer immunotherapy, claims new study

Cancer immunotherapy is a relatively new method of treating cancer and has succeeded with some refractory tumors. However, it doesn’t always work, why not?

Safe and reliable way to handle useful but foul-smelling gas in chemical synthesis

The chemical element sulfur is an important constituent in many pharmaceuticals and, consequently, it is desirable to be able to introduce sulfur-containing fragments efficiently in a broad range of chemical compounds.

Scientists report conserved role for serotonin in mediating social behavior in octopus, humans

The mood-altering drug MDMA - which promotes positive, friendly social interactions in humans by inhibiting serotonin uptake in nerve cells - has a similar behavioral effect in an octopus species, scientists report today.

Salk Institute researchers uncover molecular structure of RNA-based CRISPR system

Over the past several years, CRISPR-Cas9 has moved beyond the lab bench and into the public zeitgeist. This gene-editing tool CRISPR-Cas9 holds promise for correcting defects inside individual cells and potentially healing or preventing many human ailments.

Novel mathematical approach uncovers existence of unsuspected biological cycles

A novel mathematical approach has uncovered that some animal cells have robust 12-hour cycles of genetic activity, in addition to circadian or 24-hour cycles.

Body organs undergo structural changes in response to diet

Body organs such as the intestine and ovaries undergo structural changes in response to dietary nutrients that can have lasting impacts on metabolism, as well as cancer susceptibility, according to Carnegie's Rebecca Obniski, Matthew Sieber, and Allan Spradling.

Sea squirt model reveals key molecules in dopaminergic neuron differentiation

The human brain is exceedingly complex, consisting of various regions with particular functions and approximately 100 billion neurons. This complexity has presented a major challenge in understanding this organ and how it develops, particularly in view of the ethical issues associated with research on humans.

Researchers develop new system to detect consumption of synthetic cannabinoids

The detection has been carried out analyzing the saliva of healthy volunteers before and after they smoked these herbs along with tobacco. The samples were analyzed using high-resolution mass spectrometry (HRMS), statistical and bioinformatics methods.
